Beautiful Shots Of Glowing Bobtail Squids In The Wild

This is a series of shots from underwater photographer Todd Bretl of glowing Bobtail Squids (Sepiola atlantica) captured in their natural habitat. What is their natural habitat? Apparently pure blackness. Per Wikipedia:

Bobtail squid have a symbiotic relationship with bioluminescent bacteria (Vibrio fischeri), which inhabit a special light organ in the squid's mantle. The bacteria are fed a sugar and amino acid solution by the squid and in return hide the squid's silhouette when viewed from below by matching the amount of light hitting the top of the mantle. The organ contains filters which may alter the wavelength of luminescence closer to that of downwelling moonlight and starlight; a lens with biochemical similarities to the squid's eye to diffuse the bacterial luminescence; and a reflector which directs the light ventrally.

You ever think squids get upset that everybody likes octopuses more? I bet they do. Same goes for moths versus butterflies. Like, who wants to be everybody's second favorite, and how are you supposed to deal with that? I only ask because my brother Frank will always be the golden child and therapy is expensive.
